STOP HINGE.

Application filed March 29, 1923. Serial No. 628,627.

To all whom it may concern.

Be it known that I, JAMES P. WALKER, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Stop Hinges, of whichthe following is a specification.

This invention relates to receptacles and particularly to a stop hingeconstruction for connecting the cover to the body of a waste receptacle.

The purpose of the invention is to provide a simple inexpensiveconstruction which uides itself, is not likely to become fouled y thecontents of the can, and permits removal of the cover from the can forshipment or repair with the minimum difficulty.

The invention has particular utility as applied to the type ofselfclosing receptacle described and claimed in the patent to Ed wards,No. 1,238,993 and is illustrated as so applied in the accompanyingdrawings, in which Fig. 1 is a perspective view of the upper portion ofsuch a can, with the cover swung open to permit the receptacle to beemptied, and hence illustrating the position assumed by the stop in theopen position of the cover.

Fig. 2 is a fragmentary elevation showing the stop in the positionassumed when the cover is closed.

Fig. 3 is a fragmentary section transverse to the axis of the coverhinges showing the parts in closed position.

Fig. 4 is a similar view showing the parts in open position.

In the drawings, 6 represents the body of the receptacle reinforced atits open top by a band or strip 7. A pair of alined hinges 8, whose axisis offset so as to lie outside the receptacle and below the upper marginthereof connect the receptacle 6 and its cover 9.

This cover 9 is of the gable form, characteristic of the Edwards type ofcan and is pressed up from sheet metal. Its lower margin, whichoverhangs the upper margin of the receptacle 6, is reinforced. byfolding the sheet metal back upon itself as shown at 10, and then inwardto form a flange 11 which stifi'ens the margin of the cover and alsoserves as a seating flange which rests on the top of the receptacle 6and supports the cover. The hinge pins 12 of the hinges 8 are cotterpins so as to be capable of easy withdrawal. It will be observed thatthe hinges 8 are connected to reinforced portions of the receptacle andcover. These connections, as well as the connections of the reinforcingband? to the receptacle 6 are made by spot welding, a construction whichleads to easy assembly and good structural strength.

A bracket 13 is spot welded to the body of the can 6 and carries pivotedthereto, by

' means of a hinge pin 14, a stop arm 15.

The pin 14 is so located that when the arm 15 is arrested by collisionwith the reinforcing band 7 it lies in face'contact with the band.Absolute accuracy in this action is not essential but it is desirable toapproximate the result as clearl as commercial manufacture permits, asthis tends to reduce bending stresses exerted on the arm and band.

An angular bracket 16 is spot welded to the cover 9 in the angle betweenthe cover and the flange 11. It thus serves in some degree to stay theflange 11 and derives some support therefrom. Just beyond the margin ofthe flange 11 the bracket 16 is formed to receive a hinge pin 17. Thepin 17 serves as a connection between the bracket 16 and the link 18,whose other end is pivoted by the cotter pin 19 to the free end of thestop arm 15.

The cover 9 is formed with an opening which is closed by a pendantgravitating closure 20 pivoted at the ridge of the gable as shown at 21.This closure has two inclined surfaces conforming to the slopingsurfaces of the gable, and is tipped bodily in either direction from itsnormal position when material is to be deposited in the can.

The stop structure is thus simple, strong and, selfguiding. In theclosed position of the cover it swings down rather close to the side ofthe can so as to be out of the path of refuse delivered into the can.Furthermore, this type of stop has no tendency to become entangled withthe bag (not shown) which commonly is suspended within cans of this typeto receive the refuse.

What is claimed is 1. The combination of a receptacle, a cover hingedthereto on an axis outside the receptacle and below the upper marginthereof; a stop arm pivotally mounted within said receptacle below theupper margin thereof; and a link pivoted to said stop arm and pivotallyconnected with said cover on an axis spaced from said hin e axis, thearts being so arranged that t e sto arm is arrested by collision with aportion of the receptacle, as the cover reaches open position.

2. The combination of a receptacle having a reinforced upper margin; acoyer hinged to said rece tacle onan axis. outside the receptacle andelow the upper margin thereof, said cover having an inward pro jectinflange arran ed. to seat on the reinforce margin of t e receptacle whenthe cover is closed a stop arm ivotall mounted within said receptacleelow t e upper margin thereof and arranged to be arrested by collisionwith the reinforced marginal portion of'the receptacle; and a linkpivotally connected with said am and pivotally connected with said coveron an axle spaced from said hinge and adjacent the margin of saidflange. I

3. The combination of areceptacle having a reinforced marginal portion;a cover of sheet material having a reinforced overhanging marginalportion formed by folding the material back upon itself and then inwardto forma flange which in the'closed position of the cover seats upon thereinforced marginal portion of the can; a bin mounted on the outer sideof the reinforced margin of the can and on the under side of t ereinforced marginal portion of said cover and serving to hinge the coverto the receptacle; a stop arm pivoted to the receptacle within the sameand adapted to be arrested by collision with the reinforced portionthereof; a bracket connected with said flange and with the cover; and alink pivoted to said bracket adjacent the margin of said flange and alsoivoted to said arm.

In testimony whereo I have signed my name to this specification.
